Agobot-ku worm???

I downloaded AVG Antispyware, and in 'Analysis -> Autostart' there is a blank file or folder.
The Spybot & Destroy says that this must be Agobot-ku worm.
The localization is in registry, but if I try to find the file - system32.exe - I can't find anything, neither with full 'my computer' search nor in 'regedit' Run folder.
Does anyone have any idea, what this could be?
Could it be a worm without the system32.exe file?
Thanks for your answers in advance.
